Steering Wheel Swap Help


Ah, disregard, I’ve carefully re-read this whole thread again and have found the connector which is cunningly concealed behind the larger, more prominent one. Happy days!
Apologies for the thread resurrection, but I'm going to be swapping out my wheel for a Sport which was recently purchased from another forum member. Stupid question time - regarding battery disconnecting, do I disconnect both terminals to do this or just + or - ? I think I saw somewhere on another Audi forum about only disconnecting one or the other. First time I've messed with airbags, so I'm a little apprehensive...
